Good one, Limey-G. You talk about perfect details being essential to likeness. It's true and I'll tell you one place that will make all the difference: If you straightened the hair on the far side of the neck where it comes into the jaw, you'll make it read better and more dimensionally. It's a small detail is all. Right now the curve implies a lack of dimension where the jaw and neck are on the same plane. On a copy, you may want to try that very slight change.
